If you're grossly overweight it's even worse! Only the most elite athletes can liberate and metabolize adipose tissue at 1/2 that rate, and so a morbidly obese individual losing weight at such rates is burning muscle.

Losing weight is far far easier than gaining strength. If the end goal is to be a fit individual and not just skinnyfat the easiest and fastest way is to lose weight more slowly and maintain the muscle.

The mountains are not free-floating on the mantle. They are attached to the entirety of the continental plate and thus not only are they supported by the plate the mantle displacement is not solely local.

What's truly amazing is how people try so hard to find any excuse to deny the genetic evidence. "Eugenics deniers" are far worse than "climate change deniers" in that the scientific evidence for eugenics is far greater than even that for anthropomorphic global warming.

It was nice of you to completely ignore the argument for "mental toughness" AKA "I had my penis mutilated as a grown-ass man and would have lost everything had I shown any sign of discomfort during the process".

If you've never competed in serious athletics (where there are a thousand people younger, stronger, and hungry waiting for you to fail so they can take your job) breathing down your neck you might not understand just how important a skill swallowing pain is.

Imagine having enough money to buy a small aircraft (and time to get a license to fly it) OR a new luxury car, but not really feeling rich enough to justify buying both

Except for the fact this car has the performance characteristics not of a private jet, but of a $40,000 used Cessna with half the seats removed and rocks in one of the fuel tanks. Anybody who can afford this can afford a comparable fixed-wing aircraft easily.

War is mate competition carried out by other means. There is no other rational for it (war is always economically irrational, although this is not generally understood because it "just makes sense" to so many people that war is somehow a good idea.)

You speak in bold assertive tones about studies and ideas (including kin selection) as if they were established truths.

You claim there is no other rational reason for war, while there is an entire rich field of study on the possible motivations for war amongst humans.

For example it was Ernest Becker who (if not developed at least) popularized the (widely held today) believe that humans war for reasons chimpanzees can't. That (and I'm going to grossly oversimplify here) our death-denial systems rely on an outsider, rely on an enemy, and if one looks past the economic value of many wars (and yes war is often economically rational too) what one will find is a clash of death-denial stories.
